Metromint was something I first saw on the show Unwrapped on the Food Network. The secret method by which this water is infused with mint and flavors without adding any calories piqued my interest, but I thought it'd be yet another product on that show I'd never see.
To my surprise, the fancy grocer down the street carried several varieties of this yuppie water. I got these flavors on sale for 3 for $5, but I don't remember what full price was.
Peppermint (not pictured) had a supposed chill factor of -9 degrees below regular cold water, and it was quite chilly. The mint reminded me of toothpaste, and it certainly seemed like a good thing to drink after eating something with a lot of garlic. The mint was cool and refreshing, but as a result, it seemed incompatible with a lot of foods (think drinking orange juice after brushing your teeth). By itself, it was a nice substitute for gum or a mint, but I can't see myself drinking it often. B
Lemonmint had a chill factor of -4 degrees, and it smelled a bit like a cough drop. It tasted like one, too. The water was a mild mint with just a hint of lemon, and even though the flavors seem at odds, it worked. This water was milder than the peppermint, and was quite refreshing. B
Chocolatemint smelled weird and a bit like a peppermint patty, but it was surprisingly good. Somehow, without any sweeteners (natural or otherwise), it tasted sweet. The water was lightly minty (just -2 degrees on the chill factor scale) with hints of cocoa, and overall, it was literally a very cool drink. B+
